ContinentalGrand Prix 4-Season Road Tire(Return to Product Page)

When the rains start and the roads fill with debris, these tires go on and the GP 5000s come off. I think this tire is a good compromise between the GP 5000s and the Gaterskins in terms of rolling resistance and puncture protection. I've only gotten one puncture in these in over 2 years, although it was a sizable nail that no tire would have survived.

My one gripe with the GP 4-Season is the sizing. I have very tight tolerance with my Ridley Noah and a 25mm tire measures nearly 27mm at 105psi. I can run 25mm with the GP 5000s, but have to run 23mm with these. Very annoying!

The Continental Grand Prix 4-Season tire is my go-to winter tire for the mild winters of California. The GP 5000s come off the bike in January and go back on in April or May. The GP 4-Seasons are not as supple, obviously, but they have good rolling resistance and puncture protection is superb. These tires handle gritty chip/seal roads with winter storm debris, twigs, small branches, small stones, etc., without concern. My BIGGEST complaint by far is the sizing! A 25mm tire actually measures 26.8mm at 7 bar and rubs on my Ridley Noah frame. I have to run a 23mm version on the rear which rides harder.

I couldn't believe it when Michelin changed the compound on their Pro4 Endurance tires (the New Power Endurance are terrible). After skating around corners for a couple of weeks I called Bike Tires Direct and asked for a recommendation. He asked if I was ready to upgrade to the Continental Grand Prix 4-Season, so I dove in head-first. These are as tough as nails and handle beautifully. Not only are these wonderful tires, but I was able to return my unused Michelins for a full refund. Win-win: a great tire from a great business! I put 3,000 miles on three sets this year and I'm not going to buy any other tire. As a 200 pound rider I usually only expect about 800 miles from a rear tire, but these easily handled over 1,000 miles. They're expensive, but worth it, and BTD puts them on sale about once a month for Gold Members.

Very durable all weather tires. Best tires I�ve owned, had Continental 4000, Gatorskins and many more.

I currently have the Continental GP 4-Season tires in both my bikes (700x25 and 700x28 sized) so you can say I really like them. I bought the 4-Season because I prefer the extra protection vs their normal racing ones, however the 4-Season tires are fast tires too. They are light, great traction and have not had any issues with them (only had 250-300 mi on them). I was riding Schwalbe One DD before, and I can say that Continental GP 4-Season seem to provide a smoother ride with better rolling resistance.

Like the 28 more comfortable ride.

I've ridden the 4-Season about 15000 miles over the past decade. This tire has good grip and a terrific feel for the road. No tire is flat proof, but this is very flat resistant. Easy to change due to kevlar beads. Average wear.

This is a Bulletproof good riding tire. I use them year round including my rain bike. Its been the tire of choice for 5 years now.

I weighed these on my digital scale. I weighed several, I think I had 4. Then weighed Conti 5,000�s AND my Gator skins.

These tires weighed more than my gator skins.

About 340 grams on average. About 100 grams more than my Conti 5000s.

So VERY HEAVY. NOT. A racing or light weight tire as I expected.

I bought 3 of these. They weight much more than advertised. The ones I got, I weighted on my digital scale, They weigh more than my gator skins.

For A 28 tire, about 330 grams. VERY heavy.

Great traction in our rainy northwest! Smooth ride, responsive turning, and I don�t have to worry about those slick spots on the road!

Beware of size change without spec change 2018

My road bike's brakes used to fit 28mm Continental Grand Prix 4 Season Road Bike Tires, now they don't. Seems Continental changed the size of the tires without changing the numbers or names or actually telling anyone. If your framebrakes used to barely fit the 28 size, the new revision will be too big.

How to tell the difference

Older 28c is embossed MAX. INFLATE TO 116 PSI - 8.0 BAR

Newer 28c has MAX LUFTDRUCKINFLATION 8.5 BAR - 115 PSI.

Flattened out bead to bead dimension of the newer 700x28c version has increased by 5mm. That extra 5mm of perimeter is enough to make them intermittently rub on SRAM Red caliper brakes on recent Bianchi carbon frame.

15 months of riding, 4,000-plus miles, 700 x 28 tires, no flats.

I do wish Conti would again offer the all-black option.

I use the Conti 4 Season Grand Prix on my weather bike - the one I ride when it is raining or just wet out. These tires grip the road in wet conditions, and they are tough enough with the Vectran to handle the extra grit that gets on everything in wet weather. We have an extremely hard quartz in our area, and this stuff is used everywhere on the roads. It is loose on the surface of paved roads, and sharp bits are embedded in the tar. The Grand Prix 4-season tires don't slice, tear, or puncture very easily so they are working out perfectly for me.

I put two new pairs of 28mm GP 4 Season tires on our bike's to stop the flats. My wife has ridden 2981 miles on her tires and she has had just one flat. It used to be you would average (on a NEW tire) about a flat for every 1000 miles you would ride (the flats would increase with the miles on the tire). My original GP4 rear tire lasted 4814 miles with 2 flats - one was a seam leak in the tube (that's not the tire's fault) and the other one was caused by a very tiny thorn which was losing about 15 lbs of air a day. I did get all the use I could out of that tire because you could see a few little places of the white cords under the tire's flat center tread before I changed it out.

I do not rotate my tires because years ago a racer told me if you blow out the front tire you are going to go down - if it is the rear tire you can still have control and ride 'er down to a stop so always put your best tire on the front axle. So I always move the used front tire to the rear wheel and put the new tire on the front. That original front tire that went to the rear position now has two tiny places in the worn flat center that are starting to show the white cord below. That tire is about due to be replaced so I will mount the front tire on the rear wheel and put a new tire on the front wheel.

The GP4 is a directional tire -- look for the rounded D's (with the cross hatches) on the outer edge of the tread butting up to the Vectran sidewall belts. The 14 short straight side of the cross hatched slanted D's should be facing toward the FRONT of the bicycle when the tire is correctly mounted.

That original tire that is now on the back has 8358 miles on it and it has had just those two flats I mentioned earlier. Today the front tire that will eventually go to the back has 3550 miles on it with no flats and the molded center line on that tire is still just visible. Most of our riding is on chip & seal, asphalt pavement but we also will get on chat, gravel and dirt lanes, too. I ride year round so I have ridden in the snow and ice down to 5 - 10 F. At those low temperatures about an hour or so is all I want. The GP 4 Season tires are superior in wet & the wetcold environments - just gear down and always keep a bike very vertical when it is very slick out.

After EACH ride we wipe the tires tread completely down with a cloth - this pulls all the junk out of the tread. You don't get very many sharp slivers that stick in the GP4 tread, unlike many other tires with softer compounds. I weigh about 190 lbs, my wife about 135. I believe this is the best pressure for ride, handling, wear & flat resistance on the 28MM tire. On both bicycles I pump the pressure up to 6 bars (87 lbs) in the rear tire and 5 lbs less in the front tire on both bikes. I loose 5 lbs of this pressure when I remove the air chuck from the tire stem. How much pressure does your chuck loose when you remove it? Have you ever checked that? So I am running 82 psi in the rear & 77 psi in the front tire. I could & should probably run a LITTLE less pressure in my wife's tires since she is 45 lbs lighter but I just haven't done the math yet. You know - you will get a better ride but with more rolling resistance. Just like life is, it has been said you have to give up something to get something Well isn't that the truth!!!

We have ridden about every ride here in the KC Mo area with the KC Bicycle Club. Rides that were all in the city, uptown downtown with glass, grates, railroad tracks, sand & everything else those city streets have for us. And the club rides out in all the surrounding countryside with gravel, thorns, cow piles, sand & chasing dogs - you know, those rural areas. This tire just simply takes everything on while you

Im a gravel cyclist for the most part, but I do a fair bit of training on the road, so I went in search a good compromise tire that handled well on road as well as some gravel, I decided to try these. And they did not disappoint!

Ive put these tires through ringer. Everything from smooth tarmac, rough gravel, sand, and some forest service roads that dont look like theyve been touched since the days of wagon trains. As to be expected, they lost traction in sand and really dusty gravel roads as well as areas of mud. But I knew that they would when I purchased them. My main concern was durability. And they went with me in places that would probably be better suited to at least a hardtail mountain bike. Not once did I ever get a flat, tear, or anything of the sort. Ive been incredibly surprised by the amount of abuse these tires could handle.

Just FYI, I ran the 32c with 50 psi front and 55 psi back.

If anybody is looking for a good all-rounder tire that they can count on, I couldnt recommend these enough!

This tire is excellent for winter training and dodgy roads especially for those training rides in the dark when you don't know what you might run over. It's no racing tire, but it's not sluggish, either. Excellent flat resistance. And it comes in a variety of sizes.

I love my GP 4000 Sii tires and have been using them for several years. I got these 4-Season ones for my fall thru spring riding, as that seems to be their intended use. I also went up to 28s for these and although they don't measure much more than my 25s when installed, I have run them with slightly lower pressures and the ride has felt very nice. While these are supposed to be tougher, I have to say that I've never had a puncture on any of my Grand Prix tires. I have however damaged them right down to the breaker before and I'm hoping this winter compound will be just a little more robust. After the snow has stopped and the PA roads have been cleaned up, I will switch back to the 4000 Sii. But for those days where I can get away from the indoor trainer during the off-season, these seem to be great choice of tire. The ride is very nice and the grip is excellent.

What can I say... these are good tires. Most of my friends use Conti's and swear by them. For me this is only second time I purchased these and I don't think I will again. I live and ride in and around NYC and within 2 weeks of popping these on I had a flat. Ok so everyone gets flats. True. However.... I have used Schwalbe's for most of my riding life (past 4 yrs or so) and I can tell you ... I RARELY, if ever, get flats. In fact I can't even remember the last one. I've ridden over 3000 miles this summer without even a whisper of a leak. The only reason I purchased the Conti was because I was about to ride my 4th or maybe 5th Century and noticed my tire had some cuts. So I thought better safe than sorry. Anyway....I've been riding Durano tires for the past 2 years with thousands of miles on them. The rolling resistance is very good, though maybe not quite as good as the Conti's but very close. So Conti users .. more power to you... I'll stick with my Schwalbe's anytime.
